【正文】 I / 52摘 要本設(shè)計(jì)為封蓋機(jī)設(shè)計(jì)，主要應(yīng)用于白酒企業(yè)，對白酒進(jìn)行封蓋，其生產(chǎn)率為 2022瓶/小時，所適應(yīng)的瓶高為 60100mm，瓶口直徑為 Φ2226mm。該機(jī)器由電動機(jī)提供動力，電機(jī)選用鼠籠式三相異步電動機(jī)，工作時，通過兩條傳動鏈輸出：一條經(jīng)過一級帶傳動和蝸輪蝸桿減速器驅(qū)動曲柄滑塊機(jī)構(gòu)使電動機(jī)轉(zhuǎn)動轉(zhuǎn)變?yōu)橹本€往復(fù)運(yùn)動；另外一條是電動機(jī)通過兩級帶傳動驅(qū)動滾壓頭中心軸做旋轉(zhuǎn)運(yùn)動，從而實(shí)現(xiàn)滾壓頭同時做旋轉(zhuǎn)、直線運(yùn)動，實(shí)現(xiàn)對瓶口的封蓋。曲柄滑塊機(jī)構(gòu)具有結(jié)構(gòu)簡單、加工容易、維修方便、經(jīng)濟(jì)實(shí)用的優(yōu)點(diǎn)，在機(jī)械設(shè)備中應(yīng)用廣泛。本設(shè)計(jì)中，通過對平面曲柄滑塊機(jī)構(gòu)的數(shù)學(xué)建模，用 MATLAB 編程，輸入曲柄滑塊機(jī)構(gòu)的機(jī)構(gòu)參數(shù)和運(yùn)動參數(shù)，實(shí)現(xiàn)對整個機(jī)構(gòu)運(yùn)動過程的仿真分析。關(guān)鍵詞：封蓋機(jī)；曲柄滑塊；蝸輪蝸桿；帶傳動II / 52AbstractThis design for sealing machine design, mainly applies in the liquor enterprise, to block of liquor, its productivity for 2022 bottles/hour, the bottle to high for 60100mm, and the bottle to diameter for Φ2226mm. This machine powered by motor, motor selection rat trap type threephase asynchronous motor, working, this through two transmission chain output: One passing level 1 belt and worm reducer drive slidercrank mechanism for linear motor rotation transformation to reciprocating movement。 another is the electromotor through twostage belt drive roller head do rotational motion, so as to realize the pressure head also do roll rotation, linear motion, realizes to mouth sealing. Slidercrank mechanism has simple structure, easy processing, maintenance is convenient, economical and practical advantages, is widely used in mechanical equipment. This design, through the plane slidercrank mechanism mathematical modeling, MATLAB programming, input slidercrank mechanism structure parameters and the motion parameters of the whole anization, realize the movement process of the simulation analysis. Keywords: Sealing machine。 Slidercrank。 Worm。 Belt transmission / 52目 錄摘 要 ....................................................................IABSTRACT .................................................................II目 錄 ....................................................................I第一章 緒論 ...............................................................1第二章 總體方案設(shè)計(jì) ......................................................2 液壓傳動檔案 .........................................................2 氣壓傳動方案 .........................................................2 機(jī)械傳動方案 .........................................................3 凸輪傳動機(jī)構(gòu) .....................................................3 曲柄滑塊傳動方案 .................................................4 設(shè)計(jì)創(chuàng)新型傳動方案 ...................................................4第三章 電動機(jī)的選擇 ......................................................6 電動機(jī)類型的選擇 .....................................................6 電動機(jī)的容量選擇 .................................................6 確定電動機(jī)型號 ..................................................7 電動機(jī)的外形尺寸 ................................................8 傳動系統(tǒng)運(yùn)動參數(shù)及動力參數(shù)的計(jì)算 ....................................8 確定傳動系統(tǒng)各部分合理的傳動比 ..................................8 計(jì)算運(yùn)動參數(shù)(各軸轉(zhuǎn)速) ..........................................9 計(jì)算動力參數(shù) ....................................................9第 4 章 帶傳動的設(shè)計(jì)及計(jì)算 ...............................................11 確定設(shè)計(jì)的功率 ......................................................11 選擇帶型 ...........................................................11 確定帶輪基準(zhǔn)直徑 ...................................................12 初選小帶輪基準(zhǔn)直徑 .............................................13 驗(yàn)算帶速 .......................................................13 計(jì)算大帶輪基準(zhǔn)直徑 .............................................13 確定中心距和帶的基準(zhǔn)長度 .......................................13 驗(yàn)算主動輪包角 .................................................14 確定帶的根數(shù) ...................................................15 確定帶的預(yù)緊力 .................................................15 計(jì)算帶傳動作用在軸上的力 .......................................16 帶輪結(jié)構(gòu)的設(shè)計(jì) .....................................................16 小帶輪結(jié)構(gòu)設(shè)計(jì) .................................................16I / 52 大帶輪結(jié)構(gòu)設(shè)計(jì) .................................................18第 5 章 蝸桿傳動設(shè)計(jì) ......................................................20 蝸桿傳動類型選擇 ....................................................20 選擇材料 ...........................................................21 蝸桿傳動的主要參數(shù)及其選擇 .........................................21 模數(shù)和壓力角 ...................................................22 蝸桿的分度圓直徑 ...............................................22 蝸桿頭數(shù) .......................................................23 導(dǎo)程角 .........................................................23 傳動比和齒數(shù)比 .................................................23 蝸輪齒數(shù) .......................................................24 蝸桿傳動的標(biāo)準(zhǔn)中心距 ...........................................24 參數(shù)的選定 .....................................................24 蝸桿傳動的幾何尺寸計(jì)算 .............................................24 蝸桿傳動的受力分析 .............................................27 蝸輪齒面接觸疲勞強(qiáng)度計(jì)算 .......................................29 蝸輪齒根彎曲疲勞強(qiáng)度計(jì)算 .......................................31 蝸桿的剛度計(jì)算 ..................................................31 蝸桿傳動滑動速度計(jì)算 ............................................32第六章 勻速直線往復(fù)機(jī)構(gòu)的設(shè)計(jì)與計(jì)算 .....................................34 齒輪類型的選擇 .....................................................34 往復(fù)運(yùn)動的行程設(shè)計(jì) ..................................................35 360 度全齒齒輪的設(shè)計(jì) ................
